Three-section telescopic boom for excavators
An excavator with a telescopic arm, also known as a telescopic
boom, is a type of construction equipment that combines the
functions of an excavator and a telescopic crane. It is designed to
provide increased reach and versatility in various construction and
excavation tasks.
The telescopic arm or boom of an excavator is equipped with
multiple sections that can extend or retract, similar to the
telescopic mechanism of a camera tripod or a car antenna. These
sections are usually powered by hydraulic cylinders, allowing for
smooth and precise movement.
The main advantage of an excavator with a telescopic arm is its
extended reach. By extending the boom sections, the excavator can
reach greater distances horizontally or vertically, depending on
the configuration. This makes it particularly useful in tasks such
as digging deep trenches, reaching over obstacles, or working on
elevated surfaces.
The telescopic arm of an excavator is typically controlled by the
operator using hydraulic joysticks or controls in the cabin. The
operator can extend or retract the boom sections as needed,
adjusting the reach to match the requirements of the job.
Three-section telescopic arm
The main material we use is Q690/HG785.
Lighter and stronger
The main material of the arm tube is Q690D/HG785.
Longer service life, lighter weight and stronger.
Elsewhere, we use Q355B.
Telescopic arm
Nylon material reduces wear and tear
Our pulleys are made of POM material, which has high mechanical
strength and rigidity.
Two pulleys are at the top and the other two at the bottom, which
partially separates the high and low sections.
Pressure hoses and wire ropes reduce mutual friction. Reducing the
friction will prolong the service life. You can see the wire rope
at the top on both sides and the high pressure hose at the bottom.
There is also an adjustable bracket to tighten the hose as needed.
